Bowen and Teresa Nomura's Property 380 E. Moore Street Port Hadlock, WA 98339 Jefferson County Tax Parcels 961803208, -09 & -11 Previous Cases: SEP71-64, SEP15-61 Dear Mr. Marx and Ms. Atkins, Streamline Environmental, Inc. is pleased to submit this septic system re-design and permit application for the referenced property,owned by Michael Bowen and Teri Nomura. The proposed septic system, depicted in attached drawings, has been revised to include pressurized distribution to gravel trenches installed in a parcel owned by the applicants, located across a city right-of-way to the south of the main subject parcels. APPLICATION for UTILITY PERMIT Jefferson County Public Works approved Utility Permit UTL 15-00036 on July 10, 2015, in order to allow the applicants to cross the adjacent 15'-wide city ROW with a new sewage transport pipeline. A copy of the July 9, 2015, application is included with this letter. PROPOSED DESIGN Capacity: The applicants propose to permit and install a two-bedroom-rated system, with a peak discharge capacity of 240 gallon per day, and an average discharge capacity of 180 gpd or less. The design is intended to accommodate the existing two-bedroom house. Combined Parcel Size: 0.410 acres (17,874 SF). Drinking Water Supply: The parcel is currently served by Jefferson Public Utilities District. Topography: The site gently slopes downward to the east at about 5 to 12%. The parcel to the south,parcel 961803211,proposed for the new drainfield, slopes to the north by northeast at about 8 to 12%. 1 t Page 2 Surface Water and Drainage: No surface waters exist on the subject parcel, nor are there any indications of focused stormwater surface flow. Port Townsend Bay is about 1,400 ft east of the site. Soil Evaluation: Ten soil evaluation holes were excavated at the subject parcels to examine soils throughout (See attached Site Plan Detail with Existing Conditions). On parcel 961803209, beneath about 2 to 6 inches of sandy topsoil, light brown medium-grain sands were encountered at depths to about 14"to 24"below ground surface(bgs). Beneath this sand layer, and throughout explored areas on parcels 961803208 and -09, and the northern end of parcel 961803211, a unit consisting of previously-disturbed sand, gravel and organic debris (fill) was consistently encountered. No fill was encountered toward the south end of parcel 961803211. Beneath 26" to 32" of fine surface material, Holes 9 & 10 showed medium sands, suitable for a below-grade pressurized distribution drainfield. Site Vegetation: The site is well vegetated with grasses, non-woody plants, and several trees, including a 4 ft diameter conifer. Drain Field Sizing: Using an application rate of 0.8 gals per day per square foot, consistent with Soil Type 3, the proposed drainfield would require at least 300 square feet of infiltrative surface, to accommodate a peak flow of 240 gal/day/pod: 240 gal/day-0.8 (gal/day)/ft2=300 ft2 Drainfield Positioning: The proposed pressurized drainfield would consist of five 20-ft long by 3 ft wide gravel trenches, installed on horizontal surfaces excavated 30 to 36 inchdes below grade, as shown on the include Site Plan with Proposed Septic System Layout. Excavated Trenches must penetrate sandy soils found at 26"to 32"below grade by at least 4"to 6". System Dosing Frequency and Volume: The pressurized drainfield would receive up to 10 doses per day, at about 24 gals per dose, at a frequency of one dose every 144 minutes (at peak capacity). Septic System Operations & Maintenance The property owners will record an active monitoring agreement to the property title,prior to permit finalization, in accordance with County requirements. State law requires this alternative septic system to be inspected every year, with an evaluation completed by qualified personnel and recorded with the Jefferson County Environmental Health Department. More frequent inspections of the system are recommended, but do not need to be recorded. Prior to permit finalization, Streamline will provide the property owners an Operations & Maintenance Manual that specifically describes this system and the best practices to be followed for maximum service lifetime. Decommissioning of Existing Septic Tank The existing septic tank will be properly decommissioned, and a Certification of Tank Decommissioning form will be completed and submitted to Environmental Health. Page 3 Design Drawings The subject site plan, soil evaluation form, and the proposed septic design are included in the attached Design Sheets.

Pipe runs equipped with long-sweep clean- outs, positioned as needed, secured at surface for expected 30-year lifetime. Control Panel: Aquaworx Control Panel Model IPC, 120 VAC, powered with two 20 Amp 120 V circuits (allowing one circuit for pump, one circuit for panel & alarm); installed within sight of pump tank. Pump Assembly: Orenco BioTube Pump Vault model PVU571819 equipped with stabilizing/lifting bracket, sump inlet screen, pump inlet filter cartridge, and pump slot. Sewage Pump: Orenco High Head Pump model PF 100511; 0.5 Hp, 120 Volt; rated for 12 gpm @135 ft of water column head, with discharge pipeline equipped with check valve and flow-control valve with integral unions. Electrical supply cord shall have ample slack to allow pump removal from BioTube without disconnecting wires. Pressure Transducer: Aquaworx Liquid Level Transducer installed on PVC pipe bracket extending to pump tank bottom to maintain fixed height of 25" from bell bottom to pump tank bottom. Signal cable shall have ample slack to allow easy removal of transducer from pump tank without disconnecting wires. Pressurized Transport Pipelines: 2-inch schedule 40 PVC from pump tank to distribution manifold (-90 ft) and 1-inch sched 40 PVC from distribution manifold to each of five gravel trenches (-100 ft). Drainfield Distribution Manifold: Single 2-inch schedule 40 PVC manifold feeds five drainfield laterals, each equipped with flow control valve and check valve. Manifold installed downhill of drainfield bed, at elevation below all laterals. Long-sweep elbows on the distal end of manifold, accessible in stabilized utility vault with lid installed to-grade, allows maintenance access to manifold and transport pipeline (for power flushing).

Streamline Environmental, Inc. , 715 Grant Street; Port Townsend,WA 98368-2405 a7I I EN NE everett@streamlineenv.com 360-821-9960 July 9, 2015 Construction Notes--Residential Septic System Septic System Layout: The septic system designer must supervise layout of the system prior to excavating. Laser leveling or similarly precise systems must be used for leveling, to ensure precisely horizontal infiltrative surfaces. Septic Tank and Pump Tank Placement: The pump tank excavation must have a horizontal bottom prior to adding bedding material. Six inches (6") of pea gravel bedding must be provided to properly support tank in order for tank warranty to remain effective. If shallow groundwater is encountered during tank installation, or if shallow groundwater is known to occur, a newly-installed pump tank should be filled with water to prevent floating, in case groundwater rises around it. Tank must be covered with a 1-ft minimum thickness compacted soil, or structural fill, to a maximum cover of 3-ft, unless a heavy load-rated tank is used. Risers: Access risers should be installed above septic tank and pump tank openings. Risers and lids should extend 2 to 6 inches above grade to prevent debris from falling into risers upon opening. Tank access risers shall be bonded to integral rings built into tank openings, using 3MTM Marine 5200 Adhesive Sealant, or equal, or better. Piping and conduit entering/leaving the pump tank shall enter the access riser above such integral rings. Piping and conduit openings shall be grouted and/or sealed, or equivalent, in order to prevent the transport of water or gases. Electric Supply: Two separate circuit breakers must be provided, in order to maintain a separate circuit for the alarm and control panel, and a separate circuit solely for the pump. All electrical equipment installed within the pump tank must be of non-corrosive material. Any wire splices installed in pump tank must be suitable for wet locations. All electrical conduit material must be non-corrosive and must be installed to prevent the transport of gases or vapors (sealed). Monitoring Ports: Future septic system inspections will be simplified with properly-installed monitoring ports at key points in the drainfield. Monitoring ports should extend down to the bottom of the drain rock layer, typically no deeper than 24 inches below the pre-disturbance ground surface. Monitoring ports must be installed during drainfield construction and prior to covering. They must be anchored by any of several means, in order to maintain their stability for several decades. Using wood or other biodegradable materials is not recommended for anchoring/ stabilizing systems.
